Renesas M30621FCPGP

Overview

M30621FCPGP from Renesas Electronics is a 16-bit flash microcontroller in the M16C/62P Group, built on a silicon gate CMOS process with an M16C/60 Series CPU core. It features 128 KB + 4 KB flash memory, 10 KB RAM, operates at up to 24 MHz (41.7 ns min instruction time), and supports industrial temperature range (−40°C to +85°C) in an 80-pin plastic QFP package. It targets embedded control in home appliances, office equipment, and industrial systems requiring integrated analog and motor control peripherals.

For engineers reviewing the M30621FCPGP datasheet, M30621FCPGP pinout, M30621FCPGP application, or M30621FCPGP equivalent, this page delivers verified technical context, validated pin functions, confirmed peripheral capabilities (10-bit ADC × 26 ch, dual 8-bit DAC, DMAC × 2, IEBus/I²C/UART), and real-world selection guidance for legacy M16C-based designs.

Technical Context

The M30621FCPGP implements the M16C/60 CPU core with 91 basic instructions and supports single-chip mode only. Its memory space spans 1 Mbyte (expandable to 4 Mbytes), with flash organized into blocks including dedicated Block A (4 KB) rated for 10,000 program/erase cycles.

Peripheral integration includes Timer A (16-bit × 5 channels), Timer B (16-bit × 6 channels), three-phase motor control circuit, CRC calculation (CCITT polynomial), watchdog timer (15-bit with prescaler), and clock generation via main/sub oscillators, on-chip oscillator, and PLL synthesizer - all operating under VCC1 = 4.0–5.5 V at 24 MHz.

FAQ

What is the maximum operating frequency and corresponding supply voltage for M30621FCPGP?

M30621FCPGP operates at a maximum frequency of 24 MHz with a minimum instruction execution time of 41.7 ns. This performance requires VCC1 = 4.0–5.5 V. At lower frequencies (e.g., 10 MHz), it supports VCC1 = 2.7–5.5 V, but M30621FCPGP is specified only for the 4.0–5.5 V range per its product code and 80-pin variant documentation.

Does M30621FCPGP support IEBus and I²C simultaneously?

Yes, M30621FCPGP supports IEBus and I²C simultaneously through dedicated peripheral modules. Pin P5₀ serves as IEBus DATA, P5₁ as IEBus CLK, while P5₂/P5₃ function as I²C SDA/SCL - enabling concurrent communication with automotive cluster displays (IEBus) and onboard temperature sensors (I²C).

What is the flash memory endurance specification for M30621FCPGP's Block A?

M30621FCPGP's Block A (4 KB) is rated for 10,000 program/erase cycles under −40°C to +85°C operating conditions, as confirmed in Table 1.8 (Product Code D7/U7). This makes Block A suitable for storing calibration data, firmware update images, or runtime parameters requiring frequent rewrites.

Is external VCC2 required for M30621FCPGP operation?

No. M30621FCPGP is an 80-pin variant of the M16C/62P Group that operates in single-supply mode with VCC1 only. The datasheet explicitly states "Use the M16C/62PT on VCC1=VCC2" for T/V versions, but M30621FCPGP (P version, 80-pin) has no VCC2 pins - all I/O and core logic run from VCC1 = 4.0–5.5 V.

How many ADC input channels are accessible on M30621FCPGP, and which ports provide them?

M30621FCPGP provides 26 total ADC input channels. Eight are accessible via Port P3 (P3₀–P3₇), eight via Port P10 (P10₀–P10₇), and the remaining ten are routed through Port P8 (P8₀–P8₅) and Port P9 (P9₀, P9₂–P9₇), as confirmed in Tables 1.1–1.3 and Figure 1.2 block diagram.
